Abstract
A tandem type brake power servo booster and toggle joint include a cylindrical member which has a first engaging portion for engaging a second engaging portion of a front power piston so that relative rotation between the cylindrical member and the front power piston can be prevented when a nut is tightened to secure the cylindrical member and the front power piston into position. In addition, a key member extends through a valve body and a hub of the cylindrical member to engage a valve plunger, and a surface of the key member which faces a push rod is spaced apart from the valve body to form a clearance between the valve body and the key member surface, thus providing the toggle joint with increased strength. In addition to the nut which serves as a stop, a second stop is formed on the hub so that the first and second stops integrally join the valve body and a center body of the cylindrical member with each other.
